Buzz for Devin v0.5.2-alpha.1

This source alpha updates Buzz for Devin to the current upstream Buzz v0.5.2 architecture while preserving the native Devin ACP integration and the fork-specific community workflow.

Highlights:

• Current upstream harness catalog and model-discovery architecture
• Provider-aware live model discovery, including OpenRouter and current gateway-backed catalogs
• Devin continues to launch through the official devin acp interface; the options shown for Devin are determined by the installed Devin CLI
• Richer human profiles with bio, website, and channel-role context
• Existing owner-only, allowlist, and community invocation controls remain intact
• macOS source installer retained for both Apple Silicon and Intel

Model availability is dynamic: the exact list depends on the selected harness, provider configuration, credentials, and what the underlying CLI or provider reports.

Update an existing macOS source installation:

./scripts/update-macos-source.sh buzz-for-devin-v0.5.2-alpha.1

This is an unsigned, community-maintained source alpha. The first local build can take 15-45 minutes. No Devin configuration or credentials are copied or modified.

Buzz for Devin v0.4.25-alpha.8

Buzz for Devin source alpha.8

This source alpha makes the agent harness choice explicit and fixes a newly disclosed dependency vulnerability before release.

Changed

• New users explicitly choose how runtime-default agents run during onboarding.
• The bundled Buzz Agent is offered alongside authenticated external harnesses, so Fizz, Honey, and Bumble do not have to consume a user's Devin account.
• Devin remains available as a first-class choice for agents that should use the official authenticated Devin CLI.
• Finish remains disabled until the selected bundled provider/model configuration is valid.
• Existing saved agent defaults are preserved; this release does not silently migrate current users.
• Updates both Rust lockfiles from nostr 0.44.5 to upstream-verified 0.44.6, resolving the malformed NIP-04 IV remote-denial-of-service advisory.

Validation

The release tree passed Security, Rust lint and unit tests, Windows Rust, macOS build, both Linux cross-compiles, all four desktop smoke shards, Relay E2E, Backend Integration, both desktop integration shards, and four multi-architecture Docker builds.

This remains a source alpha with a locally applied ad-hoc macOS signature. It does not redistribute a signed application bundle, modify Devin configuration, or inspect or copy Devin credentials. Follow the README installation command for the immutable alpha.8 tag.

Buzz for Devin v0.4.25-alpha.7

Buzz for Devin source alpha.7

This source alpha fixes the first-install handoff on macOS.

Changed

• Opens ~/Applications/Buzz for Devin.app automatically after the source build is signed, installed, and verified.
• Reports a clear manual launch command if macOS cannot open the installed application.
• Keeps the public clone flow protected from local GitHub URL rewrites.
• Includes launch-contract coverage for both Apple Silicon and Intel Macs.

The first source build can still take 15–45 minutes. Later application launches do not rebuild or reinstall Buzz for Devin.

This is a source alpha with a locally applied ad-hoc signature. It does not include a redistributed signed application bundle, modify Devin configuration, or inspect or copy Devin credentials.

Buzz for Devin 0.4.25 alpha 6

Source-only technical alpha for Apple Silicon and Intel macOS. No prebuilt binary is attached.

Install as a normal macOS app

If the official Devin CLI is already installed and authenticated, no Devin setup is required. The Mac also needs Xcode Command Line Tools and approximately 15 GB of temporary free space.

Copy and paste this complete chained command block:

cd "$HOME" &&
GIT_CONFIG_GLOBAL=/dev/null git clone \
  https://github.com/fenner888/BuzzforDevin.git BuzzforDevin-alpha6 &&
cd BuzzforDevin-alpha6 &&
git switch -c buzz-for-devin-alpha6 buzz-for-devin-v0.4.25-alpha.6 &&
./scripts/install-macos-source.sh

The clone bypass is command-scoped and prevents local Git URL rewrites from redirecting the public repository to git-manager.devin.ai. The commands are chained so checkout and installation cannot continue after a failed clone. A public clone never requires a username or password.

The installer detects Apple Silicon or Intel, builds the reviewed source for the Mac's native architecture, ad-hoc signs and verifies it, and installs ~/Applications/Buzz for Devin.app. Later launches open the installed app and do not rebuild or reinstall it. It does not require a paid Apple Developer account, bypass Gatekeeper, or inspect or modify Devin credentials.

The installed app uses the same packaged Buzz icon treatment as Buzz for Hermes.

Maintain the installation

./scripts/update-macos-source.sh <new-release-tag>
./scripts/repair-macos-source.sh
./scripts/uninstall-buzz-for-devin-macos.sh

Update and repair preserve a recoverable previous app bundle. Uninstall moves the app to Trash and leaves Buzz data, Keychain entries, and Devin credentials untouched.

Platform status

Apple Silicon has completed live Devin ACP acceptance. The Intel app build, architecture checks, signing, and full lifecycle gates have passed; first launch and live Devin ACP acceptance on a real Intel Mac remain the final experimental-support check. Linux and Windows remain source-run experimental paths.

Scope

This release provides the native local Devin ACP runtime. It does not claim model switching, Fusion, fan-out, Outposts, cloud handoff, or cloud Devin parity. Permission requests remain explicit.

Buzz for Devin 0.4.25 alpha 5

Source-only technical alpha for Apple Silicon macOS. No prebuilt binary is attached.

Install as a normal macOS app

Prerequisites: the official Devin CLI installed and authenticated, Xcode Command Line Tools, and approximately 15 GB of temporary free space.

git clone https://github.com/fenner888/BuzzforDevin.git
cd BuzzforDevin
git switch -c buzz-for-devin-preview buzz-for-devin-v0.4.25-alpha.5
./scripts/install-macos-source.sh

The installer builds the reviewed source locally, ad-hoc signs and verifies it, and installs ~/Applications/Buzz for Devin.app. Later launches open the installed app and do not rebuild or reinstall it. It does not require a paid Apple Developer account, bypass Gatekeeper, or inspect or modify Devin credentials.

Maintain the installation

./scripts/update-macos-source.sh <new-release-tag>
./scripts/repair-macos-source.sh
./scripts/uninstall-buzz-for-devin-macos.sh

Update and repair preserve a recoverable previous app bundle. Uninstall moves the app to Trash and leaves Buzz data, Keychain entries, and Devin credentials untouched.

Other platforms

Intel macOS, Linux, and Windows builders can use ./scripts/run-buzz-for-devin-source.sh as an experimental source preview. Live acceptance on those platforms remains pending.

Scope

This release provides the native local Devin ACP runtime. It does not claim model switching, Fusion, fan-out, Outposts, cloud handoff, or cloud Devin parity. Permission requests remain explicit.

Buzz for Devin 0.4.25 alpha 4 (source only)

Community-maintained, source-only preview of Buzz with the official Devin CLI as a native ACP runtime. No binary installers are attached.

Run the preview:

git clone https://github.com/fenner888/BuzzforDevin.git
cd BuzzforDevin
git switch -c buzz-for-devin-preview buzz-for-devin-v0.4.25-alpha.4
./scripts/run-buzz-for-devin-source.sh

What alpha.4 fixes:

• Uses the installed Git CLI for Cargo Git dependencies so an explicit GIT_CONFIG_GLOBAL override is honored.
• Documents the safe session-only bypass if a stale local Git rewrite redirects public GitHub URLs to git-manager.devin.ai.
• Retains alpha.3 fixes for Intel macOS pnpm bootstrapping, ~/.local/bin Devin discovery, and named preview branches.

Safety boundary:

• The launcher does not inspect, copy, print, or modify authentication credentials.
• It does not modify permanent Git configuration.
• Devin remains owner-only by default.

Validation:

• Full local just ci passed.
• GitHub hosted desktop build, core, integration, relay, and all four smoke E2E shards passed in run 30323455157.
• The affected Mac mini clone completed its source build and launched Buzz successfully.

Platform status:

• macOS source preview is verified.
• Linux and Windows remain source-builder previews pending physical end-to-end acceptance.

Buzz for Devin 0.4.25 alpha 3 (source only)

Buzz for Devin alpha 3 is a community-maintained, source-only technical preview for builders testing Cognition's official Devin CLI in Buzz.

There are no application binaries attached to this release. Clone and run the reviewed source; do not redistribute an unsigned local build.

Start here

git clone https://github.com/fenner888/BuzzforDevin.git
cd BuzzforDevin
git switch -c buzz-for-devin-preview buzz-for-devin-v0.4.25-alpha.3
./scripts/run-buzz-for-devin-source.sh

Read the platform prerequisites and acceptance checklist:

https://github.com/fenner888/BuzzforDevin/blob/buzz-for-devin-v0.4.25-alpha.3/docs/buzz-for-devin-builders.md

If the Devin CLI is not already installed and authenticated, use Cognition's documentation:

https://docs.devin.ai/cli

What alpha 3 fixes

• Intel macOS no longer fails when Hermit cannot provide a standalone pnpm 11 archive; the launcher falls back to the repository-pinned pnpm through Corepack.
• The launcher includes the official Devin install location (~/.local/bin) before checking runtime readiness.
• The documented tag checkout creates a named local preview branch, avoiding the confusing detached-HEAD warning.

Platform status

• Apple Silicon macOS: verified technical alpha; full CI and live Devin ACP acceptance have passed.
• Intel macOS: corrected source path is published; physical-machine end-to-end acceptance is the remaining confirmation.
• Linux x86_64 / ARM64: source preview and CI compilation are available; live Devin ACP acceptance is pending.
• Windows x86_64 MSVC: source preview and Windows CI are available; live Devin ACP acceptance is pending.

Experimental means the source path is available for builders. It does not mean this fork publishes or supports a platform installer.

Safety boundary

• Uses Cognition's official devin acp command and each builder's own account.
• Does not inspect, copy, or modify Devin credentials or configuration.
• Keeps one-worker and owner-only defaults.
• Keeps permission decisions explicit and fail closed.
• Does not enable a bypass or persistent auto-approval mode.
• Does not claim model switching, Fusion, fan-out, Outposts, cloud handoff, or cloud Devin parity.
• Does not enable an updater or use signing credentials.

Buzz for Devin 0.4.25 alpha 1 (source only)

Developer source alpha

This is an unofficial community fork of Block's Buzz with first-class support for Cognition's official Devin CLI through devin acp. It is not an official Block or Cognition product.

This prerelease is an immutable, source-only checkpoint for trusted technical testers. No DMG or application bundle is attached. Locally built applications are unsigned and are not intended for redistribution. This is not the signed/notarized public beta.

Supported target for this alpha

• Apple Silicon macOS 11 or newer
• Verified on an Apple Silicon Mac mini
• Intel macOS, Windows, and Linux have not completed fork-specific packaging and live acceptance and are not supported by this alpha

What is included

• Native Devin ACP runtime using executable devin with default argument acp
• Runtime readiness states for missing CLI, unauthenticated CLI, authenticated/ready, and ACP startup failure
• Official Devin CLI installation and devin auth status readiness guidance
• White-background Devin runtime artwork in the existing Buzz runtime icon system
• Owner-only invocation and one-worker defaults
• Fail-closed permissions without dangerous bypass modes
• Fork-isolated app identity, data directory, Keychain service, Nest, CLI link, and deep-link scheme

This does not claim model switching, Fusion, fan-out, Outposts, cloud handoff, or cloud Devin parity.

Build and install from this exact source

Install and authenticate the official Devin CLI first using Cognition's documentation: https://docs.devin.ai/cli

git clone https://github.com/fenner888/BuzzforDevin.git
cd BuzzforDevin
git checkout buzz-for-devin-v0.4.25-alpha.1
. ./bin/activate-hermit
./scripts/build-buzz-for-devin-macos.sh
./scripts/install-buzz-for-devin-macos.sh \
  "desktop/src-tauri/target/aarch64-apple-darwin/release/bundle/macos/Buzz for Devin.app"

The build script does not sign, notarize, publish, launch, or install the application. Review the complete macOS source-build instructions before proceeding. Do not bypass organizational security policy or redistribute the unsigned local build.

Validation

Exact source commit: e71f175def60dd86d72343738ad4e4fbf65eb69d

• Focused changed E2E tests: 4 passed
• Surrounding agent E2E files: 73 passed
• Desktop formatting, lint, file-size, text-size, and pubkey guards: passed
• Full fork GitHub CI: passed, including Rust lint, unit tests, security policy, relay E2E, desktop core, macOS build, Windows Rust, mobile, web, desktop smoke shards, and relay-backed integration shards

Known limitations and remaining release gates

• Signed/notarized DMG is not yet available
• The updater remains disabled until a fork-owned signing key and HTTPS endpoint are configured
• Clean-machine acceptance remains required for the signed release
• Three inherited Apple Silicon dependency maintenance advisories remain documented for explicit release review
• Revocation takes effect after the managed agent is restarted
• Revoking a live agent instance and changing its saved definition are separate actions
• Windows, Linux, and Intel macOS need platform-specific builds and Devin ACP live acceptance before support is claimed

Generic upstream integration is tracked separately in block/buzz PR #3225.
